Title: Improvements in and relating to tobacco pipes
IPC: A24F1/08
Filed: 1965-10-29
Abstract: 1,066,780. Tobacco pipes. W. FELDER. Oct. 29, 1965, No. 45799/65. Heading A2M. A tobacco pipe has a body 1 having a longitudinal bore extending the whole length of the body through which extends an extension 24 of the mouthpiece 5 and between the bore and extension the moisture trap chambers are formed, one 14 adjacent the bowl and the other 17 adjacent the mouthpiece end of the pipe, the chambers being connected by a duct 26 formed between the middle portions of the extension and the bore. The bore is provided with an aluminium alloy condensing tube 2 which communicates with an insert 3, e.g. of Meerschaum, through a port 22 and insert neck 12. The insert 3 is removable from the bowl 11, is spaced therefrom by air chambers 13 and 23 and is retained in positiion by a removable rim 4. The mouthpiece extension 24 is centred in the tube 2 by ribs 21 so as to leave the smoke duct 26. Under the bowl the extension 24 is continued by a stem 15 having a plug 25 for the end of the longitudinal bore and lugs 16 which prevent condensation from flowing back into the bowl. The tube 2 forms chamber 14 around the stem 15 communicating with the passage 26. The passage 26 communicates at the mouthpiece end with the chamber 17 from which smoke is drawn by the smoker from bores 18 and 20. On withdrawal of the mouthpiece 5 and extension 24 from the body 1 the plug 25 cleans the tube 2.

Title: Method of and an arrangement for automatically isolating a faulty section of a power line forming part of an electrical energy supply network
IPC: H02H3/06
Filed: 1974-10-25
Abstract: 1481236 Protecting power lines ZELLWEGER USTER Ltd 25 Oct 1974 [23 Nov 1973] 46219/74 Heading H2K In a protective system for a sectionalized power line 100 in which, after de-energization of the line following a fault, the faulty section is isolated and the remaining sections automatically reconnected to the supply, each section switch 102-105 that has opened owing to the passage of a fault current therethrough transmits back (i.e. in a direction opposite to the direction of energy flow during the fault) along the line itself a control signal instructing the preceding switch to close. Thus for a line connected to power supplies 2*, 2** at both ends, all the section switches 102-105 and the two main circuit breakers 8, 8<SP>1</SP> at the two ends of the line will receive reclosing signals except for those switches at either side of the faulty section. For a line fed from one end only (Fig. 1, not shown) all switches up to the one at the beginning of the faulty section will reclose. The system can also be modified to cope with lines having branches (Figs. 17, 18, not shown). At each section switch, e.g. 103, is provided a fault detector 121, responding, e.g. to excess current or earth leakage, a switch controller 117, a directional relay 125, a control signal transmitter 129 and a control signal receiver 133. When the detector 121 senses the passage of a fault current the controller 117 opens the section switch 103, and at the same time the directional relay 125 controls a change-over switch to determine to which of the two switch locations II, IV on either side the signal generated by the transmitter 129 will be sent. The receiver is coupled to the other of these two locations. If the switch 103 is at one end of the faulty section, no signal will be transmitted to its receiver 133 and the switch will remain open. Otherwise a control signal will be received from that one of the locations II, IV which is nearer the fault and the switch 103 will reclose. The timing of the opening and closing operations is arranged so that only the main circuit breakers 8, 8<SP>1</SP> have to operate under load. Preferably after opening in response to a fault the circuit breakers make one attempt to re-establish the circuit (in case the fault is only a brief one) before any of the section switches 102-105 have started to open.

Abstract: 1367167 Battery lead-in seals GATES RUBBER CO 5 Oct 1971 [7 Oct 1970] 46267/71 Heading H1B [Also in Division H2] A method of making a liquid-tight electrical connection through a wall of an electric device in particular, a maintenance-free lead-acid battery, comprises making part of the connector in the form of a socket 30 of deformable conductive material, e.g. lead, and positioning the socket against the internal surfaces of a boss 40 formed in a top wall 16 of plastics material. The plastics material has a degree of resilience and a hardness such that it may deform the material of the socket 30, a preferred material being polypropylene. A seal between the wall and the socket is made by radially expanding the socket and in Figs. 2, 3 this is performed by a blind or Pop rivet 32 (Registered Trade Mark) having a mandrel 44 which is pulled and severed to collapse the rivet as shown in Fig. 3. Electrical connection with the rivet is made by a terminal tag 42 integral therewith, the rivet being made of tin-plated steel. Figure 1 shows two such connections extending through an inner top 16 of a maintenance-free lead-acid battery 10, one tag 42 being welded to the battery top 14 and the tag (not shown) of the other connection being connected to the container 12 having a polypropylene liner 20, the sockets 30 being connected, respectively, to the positive and negative electrode plates. The battery has a vent 18 closed by a re-sealing rubber valve 24 and a carbonate pill for neutralizing electrolyte which escapes through the valve. In a modified connection, the radial expansion of the socket is obtained by a selftapping screw inserted in the socket (Figs. 4, 5, not shown). In another modification (Figs. 6, 7, not shown) the socket 30 is replaced by an annular member of lead and an O-ring is placed between the tag 42 and the upper surface of the wall 16.

Abstract: 1,119,990. Reactors. UNITED STATES ATOMIC ENERGY COMMISSION. 18 Nov., 1965 [14 Jan., 1965], No. 49009/65. Heading G6C. In a fused-salt-fueled nuclear reactor, the flow of molten lead coolant effects circulation of the fuel mass. A fertile fused salt surrounds the fissile core. In one embodiment the fuel flows upwards through graphite ducts and thermal breeding is effected. In a second embodiment, the graphite is omitted and the arrangement operates as a fast breeder. The fused-fuel 9 floats on the molten lead 2 and is circulated upwards through the graphite tubes 15, forming the thermal fission core, to the chamber 31. Molten lead coolant from the manifolds 6, urges the fuel downwards through the graphite pipes 7. The lead leaving the pipes 7 merges with the upper surface of lead 2. The breeding region 8 is cooled by lead from the manifolds 10 which falls through 8 to form the layer 11, connected to 2 by the pipes 32. Each tube 15 is free to expand axially downwards. The molten fuel may be stored sub-critically in the space 14 by increasing the gas pressure in the space 26. The fissile and fertile materials are fluoride salts of uranium and thorium respectively. In the fast reactor a downward flow of molten lead causes circulation of the fuel within a central container.

Abstract: 1515000 Cooling extruded materials TELEFONAKTIEBOLAGET L M ERICSSON 28 Nov 1975 [2 Dec 1974] 49115/75 Heading B5A An extruded thermoplastics sheathing 12 on a wire, is cooled by a mist of liquid cooling medium in passing from the extruder, in a downward or upward direction, along a passage to whose inner wall the liquid, e.g. water, is delivered, to be formed into the cooling mist by jets of gaseous medium, e.g. air, blown through openings 30 in the passageway wall to atomize the water into the mist. The adiabatic expansion of the gas from the openings may be to a temperature of below 0 C., with cooling of the thermoplastics being effected initially by vaporization of the mist, and thereafter by a rise in the mist temperature. The sheathed wire preferably passes from the extruder both upwardly and downwardly along the passageway, via a pulley 23, as in the Fig. 1 and 2 embodiment, or downwardly and then upwardly as in Fig. 3 (not shown). In the Fig. 2 and 3 embodiment, the passageway is defined by the inner, of inner and outer pipes comprising successive pipe sections 16A, 17A, and 16B, 17B, with the water being delivered to an end of each pipe section at an annular orifice 34 to trickle down the inner wall of the pipe section, and the air being delivered to the openings 30 at the same end of each section, via an inlet 22 to between the pipes 16A, 17A. The openings 30 are directed obliquely to the direction of movement of the wire and may have a component which is radial to, or radially inclined to the inner wall of the pipe 16A, to cause helical rotation of the air around the wire. A drainage box 19 which connects the wire inlet and outlet ends of the passageway, has a vent 24 to atmosphere and drainage outlets 35. To prevent water trickling down the wire at the passageway inlet and outlet, nozzles 37 are provided to blow air upwardly along the wire. In the Fig. 3 embodiment (not shown), a drainage outlet is provided at the lower end of the passageway, beneath the pulley, but the drainage box at the upper end of the passageway is provided with a nozzle, similar to that, 37, of the Fig. 2 embodiment, only at the outlet of the passageway. The wire is fed through the passageway at the commencement of extrusion by a lead wire attached to a ball of plastics material which is blown through the passageway by the air jets.
